we did need:
carseatsomething with wheels for carrying baby in - pram, from-birth-buggy
*we definitely used our sling loads, ds loved it as was(is) a very huggy baby, v convenient etc ds is 2.7 and we still use it, especially for airport travelling, best thing we bought
*bare minimum newborn size as everyone buys newborn size for presents (unless they are parents themselves and remember!) and they grow so fast. ds was out of newborn size by week 2
*sunshade for buggy - we use it every day not just when it´s sunny, but also if ds goes to sleep in the buggy as it makes it dark, keeps noise out a bit and when he was smaller helped him fall asleep as he couldn't see much so less stimulation
*a book recommendation from a different point of view to the previous book choice !! "three in a bed" by deborah jackson and "no cry sleep solution" by elizabeth pantley. Both very gentle and loving books.
*other paraphernalia: baby monitor, bouncy chair ooooh yes, pile of muslins, socks from Gap (pp is 100%right, only ones that stay on)
Didn't need:
*top and tail bowl (cat uses it now, is very happy with it I believe)
*changing table (put changing mat on top of chest of drawers and tied it on, later just used it on the bed)
*nappy disposal thingy (got given one as a present, just stank, was a pain to empty and the refils cost a bomb)
There must be more but I have waffled on for long enough as usual....
